A protest may be held outside Parramatta Police headquarters tomorrow as deposed William Tyrrell lead detective Gary Jubelin walks from the NSW Police force for good.

Detective Chief Inspector Jubelin quit the force in May and faces court later this month on charges against the NSW Surveillance Devices Act.

The alleged offences were committed while the 57-year-old police veteran led Strike Force Rosann’s probe into the disappearance of toddler William Tyrrell, who vanished four years ago from the NSW Mid North Coast town of Kendall.

Mr Jubelin is facing charges of recording interviews with witnesses during the course of Rosann’s investigations.

NSW Police began an internal misconduct investigation into Mr Jubelin last year following a number of complaints.

“Those inquiries disclosed a number of recordings allegedly made at locations in Parramatta and Kendall in NSW,” a NSW police statement issued last month said.

The remains of Mr Leveson, who vanished aged 20 in 2007, were found in the Royal National Park south of Sydney in 2017 and returned to his family.

Faye Leveson told news.com.au she and husband Mark sent their “full support of Gary and ALWAYS … we have his back”.

“It will be a sad day for the people of NSW and a great irreplaceable loss to the NSWPF,” Mrs Leveson said. “We wish Gary all the best in the future, he is a great man with a big heart and a good friend.”
